    Altered axonal targeting and short-term plasticity in the hippocampus of Disc1 mutant mice [Neuroscience] (2011)
    National Academy of Sciences
    Details
    Publication Date: 2011-12-07
    Description: Carefully designed animal models of genetic risk factors are likely to aid our understanding of the pathogenesis of schizophrenia. Here, we study a mouse strain with a truncating lesion in the endogenous Disc1 ortholog designed to model the effects of a schizophrenia-predisposing mutation and offer a detailed account of the consequences that this mutation has on the development and function of a hippocampal circuit. We uncover widespread and cumulative cytoarchitectural alterations in the dentate gyrus during neonatal and adult neurogenesis, which include errors in axonal targeting and are accompanied by changes in short-term plasticity at the mossy fiber/CA3 circuit. We also provide evidence that cAMP levels are elevated as a result of the Disc1 mutation, leading to altered axonal targeting and dendritic growth. The identified structural alterations are, for the most part, not consistent with the growth-promoting and premature maturation effects inferred from previous RNAi-based Disc1 knockdown. Our results provide support to the notion that modest disturbances of neuronal connectivity and accompanying deficits in short-term synaptic dynamics is a general feature of schizophrenia-predisposing mutations.

    Quantifying rare, deleterious variation in 12 human cytochrome P450 drug-metabolism genes in a large-scale exome dataset (2014)
    Oxford University Press
    Details
    Publication Date: 2014-03-20
    Description: The study of genetic influences on drug response and efficacy (‘pharmacogenetics’) has existed for over 50 years. Yet, we still lack a complete picture of how genetic variation, both common and rare, affects each individual's responses to medications. Exome sequencing is a promising alternative method for pharmacogenetic discovery as it provides information on both common and rare variation in large numbers of individuals. Using exome data from 2203 AA and 4300 Caucasian individuals through the NHLBI Exome Sequencing Project, we conducted a survey of coding variation within 12 Cytochrome P450 ( CYP ) genes that are collectively responsible for catalyzing nearly 75% of all known Phase I drug oxidation reactions. In addition to identifying many polymorphisms with known pharmacogenetic effects, we discovered over 730 novel nonsynonymous alleles across the 12 CYP genes of interest. These alleles include many with diverse functional effects such as premature stop codons, aberrant splicesites and mutations at conserved active site residues. Our analysis considering both novel, predicted functional alleles as well as known, actionable CYP alleles reveals that rare, deleterious variation contributes markedly to the overall burden of pharmacogenetic alleles within the populations considered, and that the contribution of rare variation to this burden is over three times greater in AA individuals as compared with Caucasians. While most of these impactful alleles are individually rare, 7.6–11.7% of individuals interrogated in the study carry at least one newly described potentially deleterious alleles in a major drug-metabolizing CYP .

    Climate change and latitudinal patterns of intertidal thermal stress (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-11-02
    Description: The interaction of climate and the timing of low tides along the West Coast of the United States creates a complex mosaic of thermal environments, in which northern sites can be more thermally stressful than southern sites. Thus, climate change may not lead to a poleward shift in the distribution of intertidal organisms, as has been proposed, but instead will likely cause localized extinctions at a series of "hot spots." Patterns of exposure to extreme climatic conditions are temporally variable, and tidal predictions suggest that in the next 3 to 5 years "hot spots" are likely to appear at several northern sites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Helmuth, Brian -- Harley, Christopher D G -- Halpin, Patricia M -- O'Donnell, Michael -- Hofmann, Gretchen E -- Blanchette, Carol A -- New York, N.Y. -- Science. 2002 Nov 1;298(5595):1015-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of South Carolina, Department of Biological Sciences and Marine Sciences Program, Columbia, SC 29208, USA. helmuth@biol.sc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12411702" target="_blank"〉PubMed〈/a〉

    The replisome uses mRNA as a primer after colliding with RNA polymerase (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-11-21
    Description: Replication forks are impeded by DNA damage and protein-nucleic acid complexes such as transcribing RNA polymerase. For example, head-on collision of the replisome with RNA polymerase results in replication fork arrest. However, co-directional collision of the replisome with RNA polymerase has little or no effect on fork progression. Here we examine co-directional collisions between a replisome and RNA polymerase in vitro. We show that the Escherichia coli replisome uses the RNA transcript as a primer to continue leading-strand synthesis after the collision with RNA polymerase that is displaced from the DNA. This action results in a discontinuity in the leading strand, yet the replisome remains intact and bound to DNA during the entire process. These findings underscore the notable plasticity by which the replisome operates to circumvent obstacles in its path and may explain why the leading strand is synthesized discontinuously in vivo.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2605185/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2605185/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pomerantz, Richard T -- O'Donnell, Mike -- R01 GM038839/GM/NIGMS NIH HHS/ -- R01 GM038839-21/GM/NIGMS NIH HHS/ -- R37 GM038839/GM/NIGMS NIH HHS/ -- R37 GM038839-20/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Dec 11;456(7223):762-6. doi: 10.1038/nature07527.

    Direct restart of a replication fork stalled by a head-on RNA polymerase (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-30
    Description: In vivo studies suggest that replication forks are arrested by encounters with head-on transcription complexes. Yet, the fate of the replisome and RNA polymerase (RNAP) after a head-on collision is unknown. We found that the Escherichia coli replisome stalls upon collision with a head-on transcription complex, but instead of collapsing, the replication fork remains highly stable and eventually resumes elongation after displacing the RNAP from DNA. We also found that the transcription-repair coupling factor Mfd promotes direct restart of the fork after the collision by facilitating displacement of the RNAP. These findings demonstrate the intrinsic stability of the replication apparatus and a previously unknown role for the transcription-coupled repair pathway in promoting replication past a RNAP block.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2861996/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2861996/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pomerantz, Richard T -- O'Donnell, Mike -- R01 GM038839/GM/NIGMS NIH HHS/ -- R01 GM038839-23/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Jan 29;327(5965):590-2. doi: 10.1126/science.1179595.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Rockefeller University, Howard Hughes Medical Institute, 1230 York Avenue, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20110508" target="_blank"〉PubMed〈/a〉

    How a DNA polymerase clamp loader opens a sliding clamp (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-12-24
    Description: Processive chromosomal replication relies on sliding DNA clamps, which are loaded onto DNA by pentameric clamp loader complexes belonging to the AAA+ family of adenosine triphosphatases (ATPases). We present structures for the ATP-bound state of the clamp loader complex from bacteriophage T4, bound to an open clamp and primer-template DNA. The clamp loader traps a spiral conformation of the open clamp so that both the loader and the clamp match the helical symmetry of DNA. One structure reveals that ATP has been hydrolyzed in one subunit and suggests that clamp closure and ejection of the loader involves disruption of the ATP-dependent match in symmetry. The structures explain how synergy among the loader, the clamp, and DNA can trigger ATP hydrolysis and release of the closed clamp on DNA.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3281585/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3281585/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelch, Brian A -- Makino, Debora L -- O'Donnell, Mike -- Kuriyan, John -- F32 GM087888/GM/NIGMS NIH HHS/ -- F32 GM087888-02/GM/NIGMS NIH HHS/ -- F32-087888/PHS HHS/ -- R01 GM038839/GM/NIGMS NIH HHS/ -- R01 GM038839-26/GM/NIGMS NIH HHS/ -- R01 GM045547/GM/NIGMS NIH HHS/ -- R01 GM045547-20/GM/NIGMS NIH HHS/ -- R01-GM308839/GM/NIGMS NIH HHS/ -- R01-GM45547/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Dec 23;334(6063):1675-80. doi: 10.1126/science.1211884.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology and California Institute for Quantitative Biosciences, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22194570" target="_blank"〉PubMed〈/a〉

    Small-molecule inhibitors of the AAA+ ATPase motor cytoplasmic dynein (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-03-20
    Description: The conversion of chemical energy into mechanical force by AAA+ (ATPases associated with diverse cellular activities) ATPases is integral to cellular processes, including DNA replication, protein unfolding, cargo transport and membrane fusion. The AAA+ ATPase motor cytoplasmic dynein regulates ciliary trafficking, mitotic spindle formation and organelle transport, and dissecting its precise functions has been challenging because of its rapid timescale of action and the lack of cell-permeable, chemical modulators. Here we describe the discovery of ciliobrevins, the first specific small-molecule antagonists of cytoplasmic dynein. Ciliobrevins perturb protein trafficking within the primary cilium, leading to their malformation and Hedgehog signalling blockade. Ciliobrevins also prevent spindle pole focusing, kinetochore-microtubule attachment, melanosome aggregation and peroxisome motility in cultured cells. We further demonstrate the ability of ciliobrevins to block dynein-dependent microtubule gliding and ATPase activity in vitro. Ciliobrevins therefore will be useful reagents for studying cellular processes that require this microtubule motor and may guide the development of additional AAA+ ATPase superfamily inhibitors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3321072/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3321072/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Firestone, Ari J -- Weinger, Joshua S -- Maldonado, Maria -- Barlan, Kari -- Langston, Lance D -- O'Donnell, Michael -- Gelfand, Vladimir I -- Kapoor, Tarun M -- Chen, James K -- R01 CA136574/CA/NCI NIH HHS/ -- R01 GM038839/GM/NIGMS NIH HHS/ -- R01 GM052111/GM/NIGMS NIH HHS/ -- R01 GM052111-14/GM/NIGMS NIH HHS/ -- R01 GM065933/GM/NIGMS NIH HHS/ -- R01 GM52111/GM/NIGMS NIH HHS/ -- R01 GM65933/GM/NIGMS NIH HHS/ -- R01 GM71772/GM/NIGMS NIH HHS/ -- England -- Nature. 2012 Mar 18;484(7392):125-9. doi: 10.1038/nature10936.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemical and Systems Biology, Stanford University School of Medicine, Stanford, California 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22425997" target="_blank"〉PubMed〈/a〉

    A nonadrenergic vagal inhibitory pathway to feline airways (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-04-11
    Description: In cats anesthetized with chloralose-pentobarbital and artificially ventilated, electrical stimulation of the caudal end of the cut cervical vagus nerve has a biphasic effect on the bronchoconstriction induced by an intravenous infusion of serotonin. The response consists of a brief augmentation of bronchoconstriction followed by relatively prolonged bronchodilation. After muscarinic receptor blockade with atropine, vagal stimulation causes only bronchodilation. Vagally mediated bronchodilation is not affected by beta adrenergic blockade with propranolol, alpha adrenergic blockade with phenoxybenzamine, or adrenergic neuronal blockade with guanethidine, but is abolished by autonomic ganglionic blockade with hexamethonium. These findings support the conclusion that a nonadrenergic inhibitory nervous system is present in the pulmonary airways of the cat and that the system is supplied by preganglionic fibers in the cervical vagus nerves.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Diamond, L -- O'Donnell, M -- New York, N.Y. -- Science. 1980 Apr 11;208(4440):185-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7361114" target="_blank"〉PubMed〈/a〉

    Description: Genome-wide association studies have previously identified 23 genetic loci associated with circulating fibrinogen concentration. These studies used HapMap imputation and did not examine the X-chromosome. 1000 Genomes imputation provides better coverage of uncommon variants, and includes indels. We conducted a genome-wide association analysis of 34 studies imputed to the 1000 Genomes Project reference panel and including ~120 000 participants of European ancestry (95 806 participants with data on the X-chromosome). Approximately 10.7 million single-nucleotide polymorphisms and 1.2 million indels were examined. We identified 41 genome-wide significant fibrinogen loci; of which, 18 were newly identified. There were no genome-wide significant signals on the X-chromosome. The lead variants of five significant loci were indels. We further identified six additional independent signals, including three rare variants, at two previously characterized loci: FGB and IRF1 . Together the 41 loci explain 3% of the variance in plasma fibrinogen concentration.
